Facebook is working on a new questions and answers product that, it promises, “will be as exciting as Facebook Photos and Facebook Events.” It might also happen to totally destroy Quora, the Q&A startup that’s become the darling of Silicon Valley. Which is interesting, because Quora happens to have been co-founded by Adam D’Angelo, Facebook’s first CTO, and a longtime friend and one-time roommate of Mark Zuckerberg.

In fact, Nicholas Carson of Business Insider has found an old IM conversation in which D’Angelo essentially comes up with the idea for Facebook. Zuckerberg was trying to decide what to do with the domain name. “We could make it into a whole network like a friendster,” D’Angelo suggested. “haha. Stanford has something like that internally.” Some have theorized that bad blood cropped up when D’Angelo left Facebook, but Carlson thinks it’s more likely that the two simply came up with the same idea, again.
